Structured debugging when you're stuck and out of ideas.
Use case: Debugging
I have a bug I can't figure out. Expected: [what should happen] Actual: [what happens] Relevant code: [paste] What I've already tried: [list] Don't just hand me a fix. First, list the 4 most likely root causes ranked by probability, with the reasoning for each. Then tell me the single fastest test I can run to confirm or rule out the top one. Only after that, suggest a fix.
